Together

Tim Brassington and Millie Wilson have been together for nearly a decade and are moving from the city to the countryside for Millie's new school-teaching job. Tim is a musician whose career has stalled; he has no driver's license and still talks like he's on the verge of a big break, which quietly frustrates Millie. At their going-away party, Millie impulsively proposes to Tim in front of everyone. He says yes, but his stunned, hesitant reaction makes the moment awkward and reveals his ambivalence. Millie warns him that if they don't split up now, it will only get harder later — foreshadowing everything that follows.

They move into a small house near the woods. Millie starts her job at the local school, where she meets friendly coworker Jamie, who also happens to be their next-door neighbor. Tim is instantly insecure and wary of Jamie's easy confidence. On a hike through the nearby forest, they stumble upon a hidden underground chamber — a sinkhole with ritual objects, a bell, pew-like benches, and a strange pool. They fall into the space and, while climbing out, their thighs get stuck together, as if their skin is magnetized. They painfully peel themselves apart and escape, shaken but assuming it's a fluke.

Back home, the changes begin. One day, as Millie drives to work, Tim's body starts moving involuntarily — slammed and dragged through the house as if an invisible tether is trying to pull him after her. The farther she goes, the more violently he's thrown. Later, when Tim kisses Millie, their lips literally fuse together. They tear themselves apart, mouths raw and wounded. That night, Tim wakes choking on Millie's hair — strands lodged deep in his throat. He moves to a separate room, hoping distance will help.

It doesn't. One night a force drags them from their rooms toward each other and their arms begin to fuse at the flesh, binding them like conjoined twins. They scream and tear themselves apart, skin leaving wounds. Tim, convinced he's losing his mind, takes diazepam — and then more — hoping unconsciousness will break the connection. Meanwhile, Millie grows suspicious of Jamie's talk about "becoming whole" and the ritual chamber they discovered.

Millie goes to confront Jamie. She finds a wedding video playing: two men going through a ritual, fusing together. Jamie appears and admits he is the fused product of those two men. He explains he belongs to a cult whose purpose is to physically merge couples into one being. The underground chamber inducted Tim and Millie when they fell into it. He says he's been nudging them toward fusion, believing it will make them whole. When Millie resists, Jamie slashes her wrist. She strikes him hard enough that he splits back into two separate men. She runs.
